Abstract :
Gain-stabilised Raman amplification in a silica fibre has been realised by means of backward pumping with a continuously mode-locked Nd:YAG laser. This enabled the first bit error rate evaluation of Raman amplified laser diode light signals. The power penalty owing to gain fluctuation has been suppressed to about 1 dB even at a gain as high as 14 dB.
